|
|
|
The *btrfs* utility is a toolbox for managing btrfs filesystems. There are
|
|
|
|
|
command groups to work with subvolumes, devices, for whole filesystem or other
|
|
|
|
|
specific actions. See section *COMMANDS*.

COMMAND SYTNAX
|
|
|
|
|
--------------
|
|
|
|
|
|
|
|
|
|
Any command name can be shortened as far as it stays unambiguous,
|
|
|
|
|
however it is recommended to use full command names in scripts.
|
|
|
|
|
All command groups have their manual page named *btrfs-<group>*.

|
|
|
|
2014-05-19 15:49:35 +00:00
|
|
|
For example: it is possible to run *btrfs sub snaps* instead of
|
|
|
|
|
*btrfs subvolume snapshot*.
|
|
|
|
|
But *btrfs file s* is not allowed, because *file s* may be interpreted
|
|
|
|
|
both as *filesystem show* and as *filesystem sync*.

|
|
|
If the command name is ambiguous, the list of conflicting options is
|
|
|
|
|
printed.
|
|
|
|
|
|
|
|
|
|
For an overview of a given command use 'btrfs command --help'
|
|
|
|
|
or 'btrfs [command...] --help --full' to print all available options.
